craft production
prod. processes based on manual skills. small scale so low economy of scale, high labour costs
mechanised production
prod. processes where machines are controlled by humans. higher cost for training and machinery, lower consumer choice
automated production
machines controlled by computers. higher cost of equipment, higher productivity
assembly line production
products and components are moved continuously along a conveyor. components are added until product is assembled
CNC
computer numerical control;
computer control of machines to manufacture complex parts. cad file interpreted by cnc machine
mass production vs mass customisation
idk
